WINDOW VENTILATOR.

AppIication filed October 20, 1925.

My invention relates to window ventilators especially adapted for use in large windows and more particularly to the means for opening and closing the ventilator.

In at large window ornamented with stained glass, such as used in churches and other buildings, a ventilator is located near The objects of my invention are to pro vide simple and eflicientmeans for opening and closing a ventilator which will not obscure the ornamentation of the window, which will be practically unnoticeable, noiseless and convenient to operate, and which will hold the ventilator in any posi- 'tion.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a front view of a window having my invention applied thereto,

Figure 2 an enlarged section on line 2--2 of Figure 1,

Figure 3 an enlarged fragmentary edge view of the window shown in Figure 1, illustrating the parts in another position,

Figures 4: and 5 enlarged fragmentary face views of elements which form a part of my invention, and

Figures 6 and 7 enlarged sections 'on line 66 and 77 of Figure 3.

Referring to the drawings, 1 indicates a. window having a frame 2, and 3 a ventilator pivoted to the frame at 4. The pivotal connections are disposed at the sides of the ventilator above its transverse median line so that the part below the pivots will be heavier than the part above the pivots. This lower part of the ventilator may be made heavier by adding weights or otherwise but the above method is preferred because of its simplicity and because it re- Serial No. 63,606.

quires no additional parts. The ventilator is locked in closed position to the window frame by a latch 5 secured to the upper part of the ventilator. This latch may be secured to either of the sides or the upper end of the ventilator and will function equally well. The latch may be of any suitable construction, preferably that shown in Figure 4L which consist of a spring-pressed bolt 6 pivoted at 7 on a casing 8 which is fastened to the ventilator. A keeper 9 is secured to the window frame and is engaged by bolt 6. The bolt is connected to a chain or cord 10, hereinafter called a cable, which passes over a guide pulley 11 secured to the side of the ventilator, and through a guide eye 12 secured to the window frame. The guide pulley is mounted on the outer face of the ventilator frame so that it will be positioned at one side of a vertical plane passing through the pivotal connections 4.

This enables a vertical pulling force on the guide pulley to obtain a leverage by which the ventilator is readilyswuno; to open position as shown in Figure 3. The lower end of the cable passes through a cable holder 13 which secures the cable and thereby holds the ventilator in any position. The holder has an opening 14 and a slit 15 extending from the opening. The cable is held in holder 13 by slipping one of its links in slit 15 and another link below the slit toprevent the chain from being pulled upwardly. This slit is shown as having parallel sides 16 and is adapted for use with a chain. When a cord is used the sides of the slit may converge from opening 14 so that the cord maybe wedged and secured between them and thus hold the ventilator in open position. Cable holder 13 may be secured to any part of the window frame on which it most efficiently serves its purpose.

The ventilator is opened by merely pulling on the lower end of cable 10. During the opening of the ventilator, bolt 6 is first swung from under keeper 9 to unlock the latch. On further pulling the cable the ventilator is swung open to the desired position, such as shown in Figure 3, owing to the position of the pulling force of the cable on guide pulley 11 which is at one side of a vertical plane passing through the pivotal connections 4. The cable is then made secure on cable holder 13 to hold the ventilator in open position. Guide eye 12 always keeps the cable near the window frame where it does not obscure the ornamentation of the window. The ventilator is closed by simply disconnecting the cable from holder 18 and allowing the heavier lower part of the ventilator to swing it to closed position.

It will be seen that ventilators constructed as above set forth may be easily opened and closed without producing objectionable noises, and the appearance of the window is not affected by the opening and closing means.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent is 1. In a window, a ventilator pivoted at its sides to the Window frame; a latch on the ventilator for keeping it closed; cable guiding means on the ventilator disposed at one side of a vertical plane passing through the pivotal connections; cable guiding means mounted on the window frame, a cable fastened to the latch and passing through all said guiding means, and adapted when pulled to unlock the latch and open the ventilator, and means for securing the cable to hold the ventilator in open position.

2. In a window, a ventilator pivoted at its sides to the window frame and having the part below the pivotheavier than the part above; a latch on the part above the pivot for keeping the ventilator closed; cable guiding means on the ventilator disposed at one side of a vertical plane passing through the pivotal connections; cable guiding means mounted on the window frame below the pivotal connections; a cable fastened to the latch and passing through all said guiding means and adapted when pulled to unlock the latch and open the ventilator, and a cable holder adapted to secure the cable to hold the ventilator in open position.

3. In a window, a ventilator pivoted at its sides to the window frame and having the part below the pivot heavier than the part above; a latch on the part above the pivot for keeping the ventilator closed; cable guiding means on the ventilator near the side edge thereof above the pivotal connections and disposed at one side of a vertical plane passing through the pivotal connections; cable guiding means mounted on the window frame below the pivotal connections; a cable fastened to the latch and passing through the guiding means and adapted when pulled to unlock the latch and open the ventilator, and means for securing the cable to hold the ventilator in open position.

I. In a window, a ventilator pivoted at its sides to the window frame and having the part below the pivot heavier than the part above; a latch on the upper part of the ventilator for keeping it closed; a pulley secured to the side of the ventilator above its pivotal connections and disposed at one side of a vertical plane passing through the pivotal connections; a guide eye mounted on the window frame below the pivotal connections; a cable fastened to the latch and passing through the pulley and the guide eye and adapted when pulled to unlock the latch and open the ventilator, and a cable holder 011 the window frame for securing the cable to hold the ventilator in open position.

In testimony whereof I have signed my name to this specification.
